Research summary:
Most of Earth's fresh water is actually underground! How soils hold water as well as allow it to move underground is what our purpose is for our IScience Project! Surface water movement causes rocks and landscapes to erode because as the water moves it picks up particles and sediments and transport them to various locations around the target. The same thing happens underground as groundwater moves through the soil and rocks there which is called Permeability and Porosity! Groundwater movement has great impacts on the landscape similar to a sinkhole! Permeability and porosity affect soil by how fast water goes through the soil. Porosity is the quality of being porous or being full of tiny holes. Liquid goes right through thing that have porosity. Permeability is how slow or quick water soaks into something! …show more content…
We were interested in this experiment because we were recently studying the layers of the earth and we thought it would be interesting to learn soil porosity. Porosity or pore space is the amount of air spaces between soil particles. During our experiment we found out that the more volume of water there was the faster it moved. The more volume of water that can go through the soil the faster it moves, resulting in more porous soil!
We conducted an experiment that tested how water flowed through three different types of soil:
